Document Summary
How we get food is tied up with sociality and cooperation and our competition key to our environment. Every new generation faces new problems: evolutionary lag. Makes a constraint: bodies might not adapt well for this new environment, ex. Upright posture without absorbing too much sunlight only head exposed directly, backpain later in life, today less walking more sitting, circulation has to go all the way up,stability problem. There are gaps between our adaptations and different environments. Allocation of energy time and risk across lifespan = strategy . Getting bigger quicker to not get constraints in late life. But if you stop eating later = malnutrition. Longer juvenile stage lets us have a longer longevity: makes us good at reproducing and being alive longer. Sex,environment: life history traits that go with being male/female. Menopause: ovarian function shuts down before everything else. Fat storage : in different stages when babies,when pregnant.
